I work for DeWalt, in product development. The DeWalt line is meant for pros and "prosumers" that want high quality, long lasting tools. For occasional home use, these tools are probably overkill. They do work well though, and once you settle on a battery platform (DeWalt 20V or Black and Decker 20V) it's nice to have multiple tools work on the same packs. The DeWalt line is pretty extensive, so the recip saw and impact driver and the hammer drill can all run on the same packs. Thus, you need fewer packs and can simply buy bare tools. The Li-ion packs are a significant portion of the cost of the tools.
